Mueller is also set to release memos about former Trump national security adviser Michael Flynn and Trump's former lawyer Michael Cohen this week, which are all likely to provide greater insight into the inner workings of the special counsel's probe into possible ties between Russia and the Trump presidential campaign.

Prosecutors on Mueller's team have been telling defense lawyers that they are "tying up loose ends" in the investigation, which has been going on for more than a year, Yahoo News reported.

Carr declined to comment to The Hill.

Some have speculated that Mueller would keep Manafort's memo under seal in order to avoid the public disclosure of additional crimes that Mueller believes Manafort committed.

But Carr told Yahoo News that Manafort's memo will be released publicly, though some parts might be redacted.

The government last week accused Manafort in court filings of breaching his plea deal, saying he “committed federal crimes by lying to the Federal Bureau of Investigation and the Special Counsel’s Office on a variety of subject matters, which constitute breaches of the agreement.” Manafort’s defense attorneys denied the allegation.

A Northern Virginia jury over the summer convicted Manafort of eight counts of bank and tax fraud. Manafort then agreed to plead guilty to two felony charges and cooperate with Mueller's investigation.

Cohen last week pleaded guilty to lying to Congress about the Trump Organization's efforts to build a skyscraper in Russia, an element of Mueller's investigation into ties between Russia and the Trump campaign. Cohen said that he had discussed the matter with Trump further into 2016 than he initially told Congress.

Cohen over the summer also pleaded guilty to campaign finance violations, claiming that he violated campaign law at the direction of a federal candidate who later became president.

Flynn pleaded guilty last December to lying to the FBI about his contacts with former Russian ambassador Sergey Kislyak and also agreed to cooperate with Mueller's investigation.
